Anyone using Octoprice?

[sharpener]

This web site seems to provide some useful services e.g. comparing Octopus tariffs and checking for missing smart meter readings. 

Anyone else using this? Is it genuine or just a way of harvesting/selling on your data?

 

Mods can you please remove the misposting in Photovoltaics, TIA

I use it occasionally to check prices on tracker. Seems legit so far.
